A very cool combination of four rules to save power in the nights. This combination of rules activate airplane mode from 23:00 to 5:00 everyday and while in the night it deactivate airplane mode after every 30 minutes for 5 minutes to get any sms or notifications. Please download all four rules in the following order & read how to make it work below. Otherwise this won't work.
